so i tried to trigger the xt3 with the tilta nucleus nano, connected a 2.5mm male male from the motor to the fuji plug that is on the top right side of the cam.
didn't work
i thought it was just sending a basic electrical signal for the camera to start recording and stops recording but it must be more complicated than that.
sent tilta a message to ask them to support the xt3, hope they will do as this camera sells pretty well i guess
